MGS MOC Release No. MOC2-524, 25 October 2003

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a rugged surface southwest of Huygens Basin that is covered by large windblown ripples or small dunes. Their orientations indicate that the responsible winds came from either the northwest (upper left) or southeast (lower right), or both. The more complex ripple patterns within the two large craters result from local topographic influences on the wind. This area is located near 20.1°S, 307.3°W. The picture covers an area about 3 km (1.9 mi) across and is illuminated by sunlight from the upper left.
